Dustin Diamond — who played Screech, the awkward but lovable anti-heartthrob in the 1990s sitcom "Saved by the Bell" — has been sentenced to four months in jail for a Wisconsin bar fight during which he stabbed a man.

The judge also sentenced Diamond to 15 months of probation, according to the Ozaukee County Circuit Court clerk's office.

Diamond has been ordered to stay away from the victim and from the bar in Port Washington, Wis., where the Christmas Day tussle occurred. He also must maintain "absolute sobriety" and refrain from all controlled substances until his probation ends, the clerk's office said.

Diamond, 38, has been ordered to report to jail Sunday evening, the clerk's office said. He is eligible to apply for work release when necessary.

In May, Diamond was convicted of two misdemeanors stemming from the fight: carrying a concealed weapon and disorderly conduct, the Associated Press reported. He was cleared of a felony charge.

During the trial, the AP reported, Diamond told jurors that he had taken a knife out during the fight to scare bar patrons, including a woman he said had punched his girlfriend, but that he stabbed a man during the brawl only by accident. Witnesses testified that Diamond's girlfriend, Amanda Schutz, had initiated the fight.

That popping you've been hearing since Wednesday night is the sound of a generation's minds being blown by Jimmy Fallon's long-promised "Saved by the Bell" cast reunion, which happened on "The Tonight Show."
